just did this job yesterday and all i can say: PITA!!!!! those bolts on the frame gm must have used loctite b/c they were hard as hell to remove!! i didnt have any pneumatic tools, good old fashion elbow grease and my hands, back, stomach, head are all aching! straight forward as stated above and the place i used to jack up the engine just enough to get the mount out is right there on the very edge of the oil pan on the drivers side (i removed the drivers side mount only) there is a "square" block that sticks out, its not too wide or big but its enough to get a 2x4 on that square and i slowly raised up on that point and it worked great. mind you, its not on the oil pan, its a very massive piece of block, there are 2 on that side but you only need to get something on one of them to raise it up. did not remove wheel liner, im only 5'7" and small so did everything from the top and underneath. those bolts are very tricky to get them back. the frame mount bolts are very easy, those 3 are right there but the other 4 well, you have to play around with the jack (up and down, up and down) but i got 2 started on one side and raised the mount to release the pressure enough to get the other 2 started. its a PITA to say the least tho!! if i had to do it again, some type of pneumatic tool would have been VERY helpful!! the frame bolts were a pain to remove, there were "stuck" on . but its done and the truck drives like new! any questions, any way i can be helpful, i just signed up after i used the info here to gather up the courage to do the job. THANKS!
